摘要:
We consider the parameterised complexity of several list problems on graphs, with parameter treewidth or pathwidth. In particular, we show that LIST EDGE CHROMATIC NUMBER and LIST TOTAL CHROMATIC NUMBER are fixed parameter tractable, parameterised by treewidth, whereas LIST HAMILTON PATH is W[1]-hard, even parameterised by pathwidth. These results resolve two open questions of Fellows, Fomin, Lokshtanov, Rosamond, Saurabh, Szeider and Thomassen (2011). (C) 2016 Elsevier Inc. All rights reserved.
